What is x if n≠m? Please help!

Answer: $80

Step-by-step explanation:

You have been told that Sarah ended up paying $60, and you were told before that the charge for a lost book was 75%.

Therefore

$60 = 75%

Now we have to find out what amount of money would be equivalent to 100%:

To do this, find out what amount of money would be equivalent to 25% first.

You can do this by dividing both values by 3.

60 / 3 = 20

75 / 3 = 25

So now $20 = 25%

Now find 100% (which is the original amount) multiply each value by 4 :

$80 = 100%

So the school payed $80 for the book.

hope this helps :)

Answer:

m= -12

Step-by-step explanation:

-15m-30=-12m+6

-3m=36

m=-12

Answer:

m = -12

Step-by-step explanation:

Simplify the Left Hand Side:

[tex]-5\left(3m+6\right) = -5\cdot \:3m+\left(-5\right)\cdot \:6[/tex]

[tex]=-15m-30[/tex]

Simplify the Right Hand Side:

[tex]-3\left(4m-2\right)=-3\cdot \:4m-\left(-3\right)\cdot \:2[/tex]

[tex]=-3\cdot \:4m+3\cdot \:2[/tex]

[tex]= -12m+6[/tex]

All together we have:

[tex]-15m-30=-12m+6[/tex]

Add 30 to both sides and simplify:

[tex]-15m-30+30=-12m+6+30[/tex]

[tex]-15m=-12m+36[/tex]

Add 12m to both sides and simplify:

[tex]-15m+12m=-12m+36+12m[/tex]

[tex]-3m=36[/tex]

Finally, we divide both sides by -3:

[tex]\frac{-3m}{-3}=\frac{36}{-3}[/tex]

And we get the answer

m = -12

Answer:

x = 8, y = 8

Step-by-step explanation:

So we know angle CAB is congruent to angle ACB so both angles are 69.

Now we add 69+69 and we get 138. Subtract from 180.

180 - 138 = 42.

Now, we set up the equation to 5x+2=42,

subtract two from both sides and get 5x = 40,

divide both sides by 5 and you get x=8.

You can simply plug in x to 5 and add two and still get 42.

The difference btwn 2 villages is over 24km Write this as an algebraic statement

To solve :

Let us represent the two villages with an alphabet :

Let:

Village 1 = x

Village 2 = y

The difference between the two villages : |Village 1 - Village |, that is x - y

The difference is more than 24 km, that is > 24

Hence,

Algebraically,

|x - y| > 24

Answer:

its D 2/6

Step-by-step explanation:

From the given options 2/6 has a repeating decimal form. Therefore, option D is the correct answer.

From the given options we need to find which number has a repeating decimal form.

A repeating decimal or recurring decimal is the decimal representation of a number whose digits are periodic (repeating its values at regular intervals) and the infinitely repeated portion is not zero.

Now, from option A:

1/5=0.2

From option B:

11/25=0.44

From option C:

3/20=0.15

From option D:

2/6​=0.3333333

From the above calculation, we can see that number 2/6 has a repeating decimal form.

Therefore, option D is the correct answer.

Step-by-step explanation:

As x goes up by 1, f(x) goes up by 2. The next line of the chart would be ...

  x = 4+1 = 5; f(x) = 9+2 = 11

The appropriate choice is f(5) = 11.

Answer:

EF / LM = 1 / 4

Step-by-step explanation:

Transformation is the movement of a point from its initial location to a new location. Types of transformation are reflection, translation, dilation and rotation.

Dilation is the enlargement or reduction in the size of a figure. If a point A(x, y) is dilated by a scale factor of k, the new point is at A'(kx, ky).

Translation is the movement of a point right, left, up or down. If a point A(x, y) is translated a units left and b units down, the new point is at A'(x - a, y - b).

Translation preserves the size and shape of an object. Dilation preserves the shape but not the size.

Cdef maps to jklm with the transformation (x,y) to (4x,4y) to (x-4,y-9).

CDEF was first dilated by a scale factor of 4 to get (4x,4y) before it was translated by (x-4,y-9). Since dilation changes the size of the figure, hence JKLM would be 4 times the size of CDEF. Therefore:

LM / EF = 4

EF / LM = 1 / 4

Answer:

Yes, it makes it true

Step-by-step explanation:

Plug in 3 and 10 as x and y into the inequality:

y > 2x + 2

10 > 2(3) + 2

10 > 6 + 2

10 > 8

Since 10 is bigger than 8, this inequality is true.

So, (3, 10) makes the inequality true.

13x=2(5x+3)

13x=10x+6

13x-10x=6

3x=6

x= 6/3

x=2

Answer:

x=2

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

13x=2(5x+3)

13x=(2)(5x)+(2)(3)(Distribute)

13x=10x+6

Step 2: Subtract 10x from both sides.

13x−10x=10x+6−10x

3x=6

Step 3: Divide both sides by 3.

3x/3=6/3

Answer:

7.5

Step-by-step explanation:

Fraction used for kite = 3/8

Fraction of entire ribbon = 1/1

Fraction left after making kite :

Fraction left = 1 - 3/8 = (8 - 3) / 8 = 5/8

Fraction used as tie = 1/12

Number of ties obtainable from the fraction left :

Fraction of ribbon left ÷ fraction used as tie

5/ 8 ÷ 1/ 12

5/8 * 12 / 1

= 60 / 8

first term: 5x-5y

common difference: -x/2 + y

The common difference is d = -0.5x + y and the first term is 5x-5y

The nth term of the geometric progression is expressed as:

[tex]T_n=a+(n-1)d[/tex]

where;

The fifth term of the sequence is expressed as:

[tex]T_5=a+4d=3x-y[/tex]

[tex]T_{11}=a+10d=3x-y[/tex]

Take the difference of the terms:

[tex]4d-10d=3x-y-5y\\-6d=3x-6y\\d= -0.5x+y[/tex]

Get the first term:

a = 3x - y - 4(-0.5x+y)

a = 3x - y + 2x - 4y

a = 5x - 5y

Hence the common difference is d = -0.5x + y and the first term is 5x-5y

Answer:

y = -4x + 5

Step-by-step explanation:

Here, we want to get the equation of the line that passes through the given points

The general form is;

y = mx + b

where m is the slope and b is the y intercept

To find the slope, we use the slope formula

this is ;

m = (y2-y1)/(x2-x1)

(x1,y1) = (0,5)

(x2,y2) = (2,-3)

m = (-3-5)/(2-0) = -8/2 = -4

To get the y-intercept we simply substitute one of the points

But we know that the y-intercept is the y-value when x = 0

From the point we can see (0,5) which means that the y-intercept is 5

so the equation of the line is;

y = -4x + 5

The equation of the graph in slope intercept form is y = -4x + 5

Using slope intercept equation

y = mx + b

where

m = slope

b = y- intercept

Therefore,

Let's take 2 coordinates to get the slope.

(1, 1)(0, 5)

y-intercept  = 5

Therefore,

m = 5 - 1 / 0 - 1 = - 4

y = -4x + 5
